To all. whom it ma concern:

Be it known that 1,, GEORGES IMBERT, a subject of the German Empire, residing at 54 Gugelstrassa.Nuremberg, Bavaria, Germany, have invented'a new and useful Process for Producing Dichlor-Ethoxy-Ethylene, of which the following is a description.

1 ,The production of di-chlor-ethoxyeethylene is'described in the British Patent N 0.678-Of {Q906 According to .this patent, trichlorethylene or acetylene tetrachlorid is subjected to the action of potassium or sodium ethylate. The reactionmay be explained by the following equation 5-- I The technical a plicationof this process involves the emp oyment of absolute alcohol and alkaline metals, which are very expen- 20'.

sive substances. I

My ex eriments have shown that the ethyl-.

.ate emp oyed in the process covered by the said patent may be replaced by aireagent obtained by boiling asolution or 'a suspension. of caustic alkali'in alcohol-which need not be absolutewith suitable means for ablowed to flow in, whereupon the temperature v is raised to boiling point.

The product of the reaction is obtained by distillation or is taken off by steam. The output attained is: very favorable; I claim as my. invention A process for producing di-chlor-ethoxyethylene from trichlor-ethylene, which consists in allowin the latter to act'upon a reagent obtained y boiling an alcoholic solutionof caustic alkali with suitable water 'ab- 5 sorbing substances. In testimony whereof I aflix my signature in the presence of two witnesses.
